pip common commands

View the path of pip

where pip

View pip version

pip -V
pip --version

pip upgrade command

python -m pip install --upgrade pip

If the network connection of the default source of pip is poor, temporarily use this mirror station to upgrade:

pip install -i pip -U

Installation package


pip install package_name  #Package here_ Name is the name of the third-party library to install

The second (recommended, faster download): use the domestic image source

pip install package_name -i 

Domestic image source

  • Alibaba cloud: (recommended)
  • Tsinghua University:
  • Watercress:

Third (specify package version number):

pip install package_name=Version number 

Fourth (local file installation):

  • Download package:

  • Search package name

  • Find the corresponding version

  • Click download

  • Download the corresponding whl file (my python version is 3.8, and my computer windows 64 bit)

  • Execute installation command

    pip install C:\Users\Administrator\Downloads\pymssql-2.2.2-cp38-cp38-win_amd64.whl #Followed by the package path and package name
  • Installation succeeded:

Global set mirror source address

It's too troublesome to add a domestic image address for each installation. You can set a fixed configuration

pip config set global.index-url

Search package

pip search package_name
